Unfortunately - yes. She wouldn't be running if she didn't.
That has been my contention. This is not just some grandiose fantasy like Biden or Kucinich or Hagel or Huckabee. Hillary is not one to set herself up for public humiliation or repudiation. She did that to get BillyBoy elected and she won't be doing it again. If she tests the waters and stays in, we got trouble in River City. Beware the security Mom and her sweet reason.
